Looks like the lpf temperature depends on the op-s in the i/v because with the ad797 they get really hot, i could not meause the temp with the infra thermometer because they are so small but feels like they are arund 65-70°C.

Plugged my JH16, and I can hear a faint sound at 0 volume. max I can bare is 8:00.

I am 99% sure that there is no gain switch, Asus come on.... A jumper, but where? at least provide instructions!

"Raja explained howthe three Essence One versions differ to reflect the price structure of and for the Standard, Plus and Muses respectively. "The difference is in the op-amps. The only other minor change is that we included a gain jumper on the Muses Edition. This alters the output voltage for someone who wants to use IEMs which won't require as much gain as over-the-ear designs. Setting that jumper to the alternate position lowers the gain and thus achieves more range over the volume control. The Plus Edition includes 4 x TI-OPA2132PA and 2 x NS-LM4562NA that can be interchanged with the standard NE-5534. The Muses Edition simply has the version 01 Muses by default as the very best we've found. It thus ships with no other op-amps to swap. If a user wanted swap options out of the box, the Plus Edition would be the one. For obvious reasons the Plus includes a screw driver and two IC clamps plus step-by-step instructions and the op-amp guide of our listening impressions. The Muses op-amps are of limited supply and ..."

The gain jumpers should be next to the headphone volume pot - to the left of it on the upper side of the PCB to be exact, and there should be two. If your unit does not have them let me know. I have relayed this to HQ already. They are on CNY break but will be back next week. If the jumpers are not present for whatever reason we will swap the unit for you, and if need be issue a recall of any or all affected units. Sorry for any inconvenience.

Wouldn't it be easier if you could show us an illustration? A picture speaks a thousand word, I'm sure you know that...and you let a user that paid a premium to search high and low for it.

Thank you, I think its not there, please can you show me where it should be in the below pictures:

I will be waiting for someone to pm/email me for a a racall, I am really disappointed!!!!! I spent 1 month looking till I found someone who can ship it, then to resend it and wait for a replacement!!!

I am a proud owner of Asus Transformer T700, P8z77- Deluxe, Asus 3D LCD,O!Play ..I lost count of how many Asus products I have..Nvidia 570GTX..

So sorry about this. We will put this right for you, hold tight please. I will be here to help anyone with this problem. The CNY break is not helping me be as quick as I'd like, but am pushing as hard as I can to get this resolved ASAP.
